Using the camshaft locking tool (P/N 529 035 926),
lock the camshaft at TDC compression position to
prevent timing chain stretching.
1. Camshaft locking tool
2. Camshaft screw
3. Camshaft timing gear
Lock crankshaft at the TDC compression position
to have the crankshaft position defined for reas-
sembly (refer to CRANKSHAFT/BALANCER

For crankshaft timing gear, refer to CRANKSHAFT/
BALANCER SHAFT.

tabs are located into the flat zone of the camshaft.
The printed marks on the camshaft timing gear
have to be parallel to the cylinder head base. See
the following illustration for a proper positioning.
